The Shōshinge (正信偈) or The Hymn of True Faith was written by the founder of Jōdo Shinshū Buddhism, Shinran.
It consists of an outline of the Pure Land teaching according to Shinran's personal interpretation.
The structure is as follows: The Shōshinge is followed by six verses from Shinran's Sanjō Wasan.
In the past Hongan-ji temples chanted the Shōshinge and Wasan daily at 6am, but some Jōdo Shinshū temples now reserve the Shōshinge for special holidays due to its length.
